Estimating Plant Available Soil Water (SWApp)

Update: SoilWaterApp V3 was released to the App Stores on 10th November 2016.

SWApp provides farmers and advisers with a ready estimate of plant available water (PAW) in the soil during a fallow and early crop phase. SWApp estimates soil water (PAW) using a tested water balance model (Howleaky) and inputs from:

weather data from a nearby Bureau of Meteorology (BoM) sourced from the Silo (https://www.longpaddock.qld.gov.au/silo/);

SWApp considered all components of the water cycle on a daily basis and uses long term climate data to provide a forward-looking estimate of likely outcomes for the specified soil, location and fallow/crop conditions.
